creatine

 [kre´ah-tin]
a nonprotein substance synthesized in the body from three amino acids: arginine, glycine (aminoacetic acid), and methionine. Creatine readily combines with phosphate to form phosphocreatine, or creatine phosphate, which is present in muscle, where it serves as the storage form of high-energy phosphate necessary for muscle contraction.
creatine kinase an enzyme catalyzing the transfer of a phosphate group from phosphocreatine to ATP. It has three isoenzymes: CK1, found primarily in the brain; CK2, found in the myocardium; and CK3, found in both skeletal muscle and the myocardium. The presence of CK2 in the blood is strongly indicative of a recent myocardial infarction; it is present until about 72 hours after the attack.

A gene on chromosome 11q13.2 that encodes the first enzyme in CDP-choline pathway of phosphatidylcholine synthesis, catalysing the phosphorylation of ethanolamine; it is thought to play a regulatory role in phosphatidylcholine homeostasis.
